Re: engine skips

When you press the clutch the engine control computer senses the clutch is in and adjusts the idle speed, maybe the idle speed control motor is dirty and sticks, this will almost feel like a skip or miss, do you have any trouble codes?

When you press the clutch pedal the release/throwout bearing presses against the centre of the clutch pressure plate. This causes the metal 'fingers' -the springs- on the pressure plate to flex and release pressure on the driven plate - momentarily disconnecting the drive from engine to gearbox.

A weak pressure plate isn't fully releasing the driven plate. If you're going to do any replacing of parts - a clutch should be replaced in 3 units: Pressure plate, driven plate and release/throwout bearing.

This is a system on subarus to stop you rolling back when on a hill with the clutch depressed . The brakes should unlock as you release the clutch. There is a cable attached to the clutch fork in the engine bay. This goes to a brake actuator on the left hand side. If it isnt working corectly check the cable for wear or fraying. It may need adjusting by a mechanic.

TEst for slipping clutch is travel about 30 mph. press clutch, shift to 3rd, rev engine pretty high and release clutch, at the time of clutch release, floor throttle. If the engine continues to race, clutch not grabbing porperly, if the clutch works properly, the engine will be slowed and engauged.
You can always get a 2nd opinon from another shop.

the 85,000 mile coutch worn out issue dependes entirely on driving habits of the operators.

you have 4 cyl or V6 engine, how much free play you have on clutch pedal (take your hand press clutch in untill gets harder to push in) should only have about 1" free play, and also when you release clutch while in gear should start engaging about 1 1/2" up when releasing

To reduce clutch disc/plate problems, avoid riding the clutch whilst driving, ie having ur foot on the clutch pedal when the engine is in operation, especially wqhen the vehicle is in motion. You see the clutch disc is sandwiched between the flywheel of the engine & the pressure plate. When the driver presses the clutch pedal, the sandwiching of the clutch plate is released, so therefore no drive is being transmitted from the engine to the road wheels. This gives an effect as if the vehicle is in neutral (engine can be revved, with no movement or propulsion of the vehicle). When the driver releases the clutch pedal, the clutch disc is now sandwiched tightly causing the drive to be transmitted to the road wheels which will now cause the vehicle to be propelled.

Clutch discs are only replaced when there are problemes with clutching in and changing gears. After constant pressing of the clutch, the asbestos material on the clutch disc after a period grinds down (clutch disc becomes thinner), which in turn will reduce friction characteristics when all the elements are sandwiched. This causes a slipping effect, preventing the drive from being transmitted to the road wheels efficiently. This causes other problems such as high fuel consumption, erratic engaging of gears, hard selecttion of gears, heavy vibration of the vehicle, stalling; just to name a few. In most cases an unusual smell of the clutch disc is observed.

Also just by resting ur foot on the clutch pedal while engine is running can be dmagaing too. You see the clutch release bearing rests on the pressure plate, so when the clutch pedal is pressed by the driver, there is a degree of friction being placed on the bearing because the pressure plate is always rotating with the engine. The clutch release bearing is stationery until the clutch pedal is pressed by the driver, which sends it into the moving pressure plate, so less pressing on the clutch pedal the less friction between the bearing and the pressure plate. Only operate/press/place foot on the clutch when necessary
